Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
1. A stereoscopic image displaying apparatus comprising: a displaying panel that receives image data displaying an image and black data displaying no image for each frame section; and a polarization control panel that is located over the displaying panel and changes a polarization state, wherein the image data includes left eye image data and right eye image data, wherein the black data is positioned between left eye image data and right eye image data, the displaying panel displays the left eye image data during a nth frame section, n is a natural number, and the right eye image data during an n+ 1 th frame section, in synchronization with the displaying panel, the polarization state of the polarization control panel is changed to a left eye polarization state during the nth frame section and to a right eye polarization state during the n+ 1 th frame section, and the black data is supplied during the intersecting section between adjacent two frame sections such that the left eye image data, the black data, and the right eye image data are displayed in succession.
A stereoscopic 3D display shows left and right eye images alternately to create a 3D effect. The display panel shows an image and also displays black frames (no image) between the left and right eye images. A polarization control panel sits on top of the display panel and switches the polarization of light. The left eye image is displayed with one polarization, and the right eye image with a different polarization. This is synchronized so that the left eye sees the left image, and the right eye sees the right image. The black data is inserted during the polarization switching to reduce crosstalk between the left and right eye views. This results in a clearer 3D image.
2. The stereoscopic image displaying apparatus of claim 1 , wherein the black data is positioned at a middle polarization section during which the polarization control panel is changed from left eye polarization to right eye polarization or from the right eye polarization to the left eye polarization.
In the stereoscopic 3D display (display panel showing alternating left and right eye images with black frames in between, and a polarization control panel switching polarization), the black frames are displayed during the time when the polarization control panel is actively switching its polarization from left to right or right to left. This ensures that any light leakage during the polarization switching is masked by the black frame, further minimizing ghosting or crosstalk between the left and right eye images, leading to a better 3D experience.
3. The stereoscopic image displaying apparatus of claim 1 , wherein the displaying panel includes sub-pixels, wherein each sub-pixel includes at least two switching transistors that receive the image data and the black data in response to at least two gate signals.
In the stereoscopic 3D display (display panel showing alternating left and right eye images with black frames in between, and a polarization control panel switching polarization), each sub-pixel on the display panel (the smallest controllable element of the display) has at least two transistors. These transistors control whether the sub-pixel displays the image data (left or right eye) or the black data. The transistors are controlled by at least two gate signals. This allows each sub-pixel to be independently switched between displaying image data and displaying black data, enabling precise control over the timing of the black frames.
4. The stereoscopic image displaying apparatus of claim 1 , wherein the displaying panel includes sub-pixels, wherein each sub-pixel includes, a first switching transistor responsive to a first gate signal supplied to a first gate line so that the image data is supplied through a data line, and a second switching transistor responsive to a second gate signal supplied to a second gate line so that the black data is supplied through the data line.
In the stereoscopic 3D display (display panel showing alternating left and right eye images with black frames in between, and a polarization control panel switching polarization), each sub-pixel on the display panel has two transistors. The first transistor receives image data (left or right eye) from a data line, controlled by a first gate signal. The second transistor receives black data from the same data line, controlled by a second gate signal. By using separate transistors for image data and black data, the display can quickly switch between displaying the image and displaying black, allowing for a more seamless stereoscopic experience.
5. The stereoscopic image displaying apparatus of claim 1 , wherein the displaying panel includes sub-pixels, wherein each sub-pixel includes, a first switching transistor responsive to a first gate signal supplied to a first gate line so that the image data is supplied through a first data line, and a second switching transistor responsive to a second gate signal supplied to a second gate line so that the black data is supplied through a second data line.
In the stereoscopic 3D display (display panel showing alternating left and right eye images with black frames in between, and a polarization control panel switching polarization), each sub-pixel on the display panel has two transistors. The first transistor receives image data (left or right eye) from a *first* data line, controlled by a first gate signal. The second transistor receives black data from a *second* data line, controlled by a second gate signal. By using separate transistors and separate data lines for image data and black data, the display can switch between displaying the image and displaying black even faster, allowing for a more seamless stereoscopic experience and reduced ghosting.
6. The stereoscopic image displaying apparatus of claim 1 , wherein the polarization control panel includes, scan lines that are formed on an upper transparent substrate and separated in stripes, and a common electrode that is formed on a lower transparent substrate and overlaps the scan lines.
In the stereoscopic 3D display (display panel showing alternating left and right eye images with black frames in between, and a polarization control panel switching polarization), the polarization control panel has scan lines arranged as stripes on an upper transparent substrate. A common electrode is formed on a lower transparent substrate and overlaps these scan lines. By applying different voltages to the scan lines, the polarization of the light passing through different areas of the panel can be controlled, thus directing different images to each eye.
7. The stereoscopic image displaying apparatus of claim 1 , wherein the polarization control panel includes, a scan line that is formed on an upper transparent substrate, and a common electrode that is formed on a lower transparent substrate and has the same shape as that of the scan line.
In the stereoscopic 3D display (display panel showing alternating left and right eye images with black frames in between, and a polarization control panel switching polarization), the polarization control panel has a scan line on an upper transparent substrate. A common electrode is formed on a lower transparent substrate and has the same shape as the scan line. This simplifies the manufacturing process of the polarization control panel and enables control over the polarization of the light passing through the display.
8. The stereoscopic image displaying apparatus of claim 1 , further comprising: polarization glasses that separate an image displayed on the polarization control panel into a left eye image and a right eye image.
The stereoscopic 3D display (display panel showing alternating left and right eye images with black frames in between, and a polarization control panel switching polarization) also includes polarized glasses. These glasses separate the polarized light coming from the polarization control panel, directing the left eye image to the left eye and the right eye image to the right eye. These glasses are necessary to perceive the 3D effect created by the display.
9. A method of driving a stereoscopic image displaying apparatus comprising a displaying panel that displays a left eye image and a right eye image for each frame section, and a polarization control panel that is located over the displaying panel, the method comprising: supplying image data displaying an image on the displaying panel and black data displaying no image on the displaying panel to the displaying panel; and changing a polarization state of the polarization control panel, wherein the black data is positioned between left eye image data representing the left eye image and right eye image data representing the right eye image, the displaying panel displays the left eye image data during a nth frame section, n is a natural number, and the right eye image data during an n+ 1 th frame section, in synchronization with the displaying panel, the polarization state of the polarization control panel is changed to a left eye polarization state during the nth frame section and to a right eye polarization state during the n+ 1 th frame section, and the black data is supplied during the intersecting section between adjacent two frame sections such that the left eye image data, the black data, and the right eye image data are displayed in succession.
A method for displaying stereoscopic 3D images involves a display panel that shows left and right eye images alternately. A polarization control panel changes the polarization of light. The method involves displaying image data (left or right eye) and black data (no image) on the display panel. The black data is placed between the left and right eye image data. The display panel shows the left eye image and then the right eye image. The polarization control panel switches its polarization in sync with the images, so each eye sees the correct image. The black data is displayed during the switching to minimize ghosting.
10. The method of claim 9 , wherein the black data is positioned at a middle polarization section during which the polarization control panel is changed from left eye polarization to right eye polarization or from the right eye polarization to the left eye polarization.
In the stereoscopic 3D display method (displaying alternating left and right eye images with black frames in between, and switching polarization), the black data is displayed during the middle of the polarization switching process of the polarization control panel, when it transitions from left-eye polarization to right-eye polarization, or vice versa. This ensures that light leakage during the polarization switching process is masked by the black frames, improving the 3D effect and reducing crosstalk between the left and right eye views, resulting in a cleaner image.
11. The method of claim 9 , wherein the black data is supplied corresponding to a middle polarization section of the polarization control panel.
In the stereoscopic 3D display method (displaying alternating left and right eye images with black frames in between, and switching polarization), the black data is displayed when the polarization control panel is in the middle of switching its polarization state. This ensures that any imperfect polarization during the transition doesn't affect the image seen by the viewer, minimizing ghosting and improving the quality of the 3D image. The timing of the black data display corresponds to the period of instability in the polarization state.
